Bent Bonding Portion for Narrow Frame Wearable Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable devices, such as smartwatches, have a limited and inefficient display mode, typically requiring the entire screen to be lit up for display, which consumes power and offers a single usage mode.
Innovation Solution
A display panel design featuring a first display portion that surrounds a second display portion in an enclosed state, with both portions capable of independent or synchronized display. The first display portion includes a first bonding portion that can be bent to the non-display surface of the second display portion, allowing for flexible signal transmission and reduced frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire display screen emits light for display, then the display function is achieved, but power consumption increases and usage modes are limited
Solution Approach 1:
The display screen is divided into a first display portion and a second display portion that can be independently controlled. The first display portion can display information even when the second display portion remains off, enabling multiple usage modes (full display, partial display, or off state) and reducing power consumption by activating only the necessary portion of the screen
2Strength
If the first bonding portion is made rigid for structural stability, then structural strength is improved, but frame width increases and flexibility is reduced
Solution Approach 1:
The first bonding portion is designed with a bent configuration where it extends from the first display portion and bends toward the non-display surface of the second display portion. This curved structure reduces the frame width compared to a straight rigid connection while maintaining structural integrity through the bending geometry
Solution Approach 2:
The first bonding portion is constructed as a flexible component that can be bent to the non-display surface of the second display portion. This flexible design enables narrow frame width and adapts to different structural configurations while maintaining sufficient mechanical strength for signal transmission
3Manufacturing precision
If the first display portion is positioned far from the second display portion for manufacturing ease, then manufacturing precision is improved, but device complexity and frame width increase
Solution Approach 1:
The first display portion is positioned adjacent to the second display portion with the first bonding portion bending between them. This curved arrangement allows compact integration reducing overall device complexity and frame width while the bonding portion maintains sufficient length for reliable signal transmission and manufacturing alignment

AI summary
A display panel includes a first display portion, a second display portion, and a first bonding portion connected to the first display portion. The first display portion surrounds the second display portion in an enclosed state, and forms an included angle with the second display portion. The first bonding portion can be bent to a non-display surface of the second display portion. The first display portion includes a first display area and a first peripheral area. The first display area is provided with a plurality of first sub-pixels. The first peripheral area is located on a side of the first display area away from the second display portion and is provided with a first voltage bus, first circuit structures, first data fan-out lines and a second voltage bus that are connected to the plurality of first sub-pixels and extend to the first bonding portion.
